trust me, i'm nothing of a wolverine fanboy. he's been a very dis-interesting character for me for quite a while, and i only really began following his series near the end of the 'enemy of the state' arc. but i agree completely with you, it does sound like something a fanboy would use to justify their perception of logan's strength. the sad truth is, though, that most of these arguments are much more applicable revolving around wolverine than around, say, nightcrawler. wolverine is marvel's cash cow, and if him doing something dramatic like skewering piotr will make them money, they'll do it. and they'll justify it as above.
it does get annoying when marvel makes rules for their characters, such as strength levels and durability and whatnot, but they don't apply them to their favorites...
